I am in the process of baking and was wondering how long cake batter will last? I have it in my mixing bowl right now until the other cakes are done. So will will probably be sitting for about an hr or so...is this ok or will affect the cake in anyway during baking????

Also, hope i did'nt make a mistake by putting 3 cake pans 6, 9 & 12 in a conventional over all at one time

Thanks cc'ers....

It will be fine
